"Deborah Tavares — a Northern California resident who argues, among other things, that climate change and wireless electricity meters are tools in a plot of glo...bal domination — calls the Resilient Cities program a “diabolical” effort to manipulate people. “This a genocide program,” she says. “We are being moved now into what they call ‘resilient cities.’"

I was delighted to find that teachers in Finland provide their students with opportunities to critically evaluate the logic behind homeopathic remedies. Yes, it... is based on magical thinking of "water memory". No, it doesn't work. The math of diminishing concentrations gets dizzying pretty quickly, but I hope it made students curious (even if they may have chosen not to solve this particular problem) to go look at the answers afterward.

If more people knew what homeopaths were up to, we could curb their influence in anti-vaccine trends, and help more people get actual medical help when they need it.

"Ask many people what they think homeopathy is and you'll be told "it's herbal medicine" or "it's all-natural". Actually, it is neither of these.

Few people realise that homeopathy involves diluting substances so much that there's literally nothing left in them." http://www.1023.org.uk/

" Of course, water does not have memory, not in the way that homeopaths claim, which is a good thing. As sarcastic skeptics like to point out: What if water had... memory of all the compounds it’s ever been in contact with? There’d be a heck of a lot of poop and urine in those memories! Basically, homeopathy is a system of medicine without scientific basis, which is why it’s good that the NHS is pulling back from funding it"

It's been a bad week for homeopathy. First, the NHS in the UK has stopped funding homeopathy in London. Then, news stories appeared about research fraud and a retracted clinical trial of homeopathy for cancer in which the investigators had already been arrested. So sad!

"A journal paper claiming to show the success of a homeopathic treatment for cancer has been withdrawn by the publishers following a series of awkward discoveri...es – including the arrest of its two lead authors.

The paper, published in the journal Evidence-Based Complementary and Alternative Medicine, was retracted in late February after readers voiced concerns and a formal investigation flagged multiple ethical problems.

The subject of the paper was “psorinum therapy” and its use in treating stomach, gall bladder, pancreatic and liver cancers. Psorinum is a peculiar favourite of homeopaths, described as a substance “prepared from the fluid of blisters from scabies infested skin”."
